HENRY J. BUIBENI-IEIM, 0F PITTSBURGH, PENNSYLVANIA.

GAS-B URNER.

Application filed February 12, 1914.

To all whom it may concern:

Be it known that I, HENRY J. BUBENHEIM, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Improvement in Gas- Burners, of which the following is a specification. p

This invention has for its primary object the provision of a new and practical form of burner, wherein economy in the consumption of gas and an extremely hightemperature is prevalent by mixing the fuel gas with vapor arising from a liquid introduced into the burner. To the normal heat units contained in the fuel gas are added the gases given off by the liquid, usually water, in the form of vapor or steam, which combined gases, being thoroughly united, tends to produce an intense heat at the point of ignition. It is obvious that the desired result will be accomplished by mixing the fuel gas and moist vapor gases inside the burner, below the point of ignition. This construction is clearly disclosed in the accompanying drawings, which involves one specifically illustrated embodiment of my invention, but I reserve the right to make necessary alterations and amendments thereto which will be within the scope of the appended claims.

Referring then to said drawings Figure 1 is a plan view of my preferred form of burner having the upper apertured cover removed: Fig. 2 is an elevation in cross section of the fully assembled burner showing necessary supply pipes.

The main body portion of the burner is a hollow U-shaped casting, here shown as being circular in form, but which can be of any desired configuration, and is designated by the numeral 1, the upper extremity of the vertically disposed side walls beingprovided with flanges 2, which support a correspondingly flanged, removable and slotted cap or cover 3, the same being preferably arc-shaped as shown. Intermediate of these two members 1 and 3 is a suitable wire mesh Specification of Letters Patent.

or screen 4:, all of which foregoing elements being held together by ordinary securing bolts 5.

The fuel gas is supplied to the burner by a pipe 6, which is here shown as being connected to a centrally disposed four-way union 7, from which radiate distributing pipes 8, the outer ends of which connect to elbows 9. Joined to these elbows are vertically disposed pipes 10 which enter through the bottom of the hollow body 1 and extend upward to a point above the horizontal plane of said screenv member 4, directly underneath the apertured cap ele ment 3.

Inside the hollow body 1, preferably near the bottom portion, as shown, is a fluid supply pipe 11, the same preferably being in two sections connected by a nipple 12 to which is joined a common supply pipe 13. The outer free ends ofthese two sections of pipe are capped, and on the under side are provided with a'plurality ofescapement apertures 1 1.

Closely packed in the hollow I body 1 around the fluid supply pipes 11 and gas supply means 10, occupying practically all the space below the screen .4, is an absorbent material 15, preferably of a non-combustible nature, such as mineral wool or similar substance, which is intended to retain or act in the capacity of a wick, for the fluid supplied thereto.

Water is first supplied to the burner in the manner shown and described, thereby saturating the filling 15. Upon the gas being ignited heat thus generated throughout the burner converts the water into steam or vapor which, rising, mixes with the gas above the screen 4:, and this combination of gas and vapor produces a moreintense heat at the exterior point of ignition than could be obtained by using the gas singly.

What I claim as my invention is:

1. In a gas burner a suitable hollow body portion; a perforated cap secured to said body; a mesh intermediate of the body and cap; an absorbent filling inside the hollow body; means for supplying moisture to said to said filling; and means for supplying gas 10 filling; and means for supplying gas above to the space above the screen.
